The agreement aims to lower carbon emissions in countries across the globe in order to limit our global warming to 2°C instead of 4°C, which is our current track of warming.

Limiting warming to 2°C may not seem like a lot, but it would decrease the amount of climate change impacts currently plaguing the world, including sea level rise, extreme weather and extreme heat.

There are still some climate change effects that won’t be completely eradicated, including ocean acidification. A lot of global heat is trapped in the oceans, and decreasing our emissions won’t decrease the current heat in the oceans. But, of course, it would help the overall rate of warming.

Because of the signing, world leaders are helping combat climate change by embracing renewable energy and carbon trading.

The main aim is to keep a global temperature rise this century well below 2 degrees Celsius and to drive efforts to limit the temperature increase even further to 1.5 degrees Celsius above pre-industrial levels. Additionally, the agreement aims to strengthen capability to deal with the impacts of climate change.

To reach these ambitious and important goals, appropriate financial flows will be put in place, thus making stronger action by developing countries and the most vulnerable possible, in line with their own national objectives.
